%X Using Poly(4-methylpentene-1) (PMP) as a membrane material, and cyclohexane, trichlo-roethylene, tetrachloroethylene, and the mixture of cyclohexane and trichloroethylene as solvents, these solutions were cast to form homogeneous dense membranes, and the membrane permeation behavious for oxygen, nitrogen, hydrogen, and carbon dioxide were investigated. The results showed that gas permeation mainly occurs in amorphous region of the PMP, but also in the crystalline region. The gas permeation activation energy in VI-form crystal of the PMP was lower than that in I-form crystal.
